Public Release: 

Effect of diabetes case management among low-income minority populations

LA BioMed

In an article published in the Janaury edition of Diabetes Care, researchers in the California Medi-Cal Type 2 Diabetes Study Group have concluded that diabetes case management, added to primary care, substantially improved glycemic control compared with the control group. Researchers concluded that diabetes case management can help reduce disparities in diabetes health status among low-income ethnic populations.

Clinical sites in three southern California counties serving low-income, ethnic minority populations participated in the study. 362 Medicaid (called Medi-Cal in California) recipients with type 2 diabetes were randomized for at least one-year intervention (diabetes case managenment) or control (traditional primary care treatments) groups. Fifty-five percent of the participants were minorities.

The major study end point was glycemic control. Results of the analysis showed that the intervention group had significant improvement in glycemic control compared with the control group.

The study provides evidence that diabetes case management is feasible and can substantially improve glycemic control in a racial/ethnic minority and or low-income Medi-Cal population. The state of California Medi-Cal Managed Care Division and Center for Disease Control and Prevention funded the study, with additional support from the Research and Education Institute at Harbor-UCLA Medical Center.
